Slow response Times for transactions relating to Solution Manager

Hi all,

We recently installed a solution manager 4.0 system on one of our i570 hardware.

We have noticed that the response times for transactions relating "typically" to solution manager are a little slow(response times between 3-4 seconds) and sometimes very slow( sometimes like 12-13 seconds)...Its very random...Are these transactions typically like these ?

The transactions we are referring to are :

1) SOLAR_PROJECT_ADMIN - Project Administration (esp when we try to select a project and double click on it to edit/display the project)

2)RMMAIN - Roadmap

3)SOLUTION_MANAGER - Solution Operation

One thing, which we though have noticed that inspite of the system being up and used for almost a 4-5 days..the hit ratio for the Initial Records Nametab buffer is an abysmal 4-5%. The settings for initial Record buffer is:

rsdb/ntab/irbdsize 13500 kB

rsdb/ntab/entrycount 45000

Shouldn't the hit ratio for this Initial Records Nametab buffer be close to a 96-98% or better...We are wondering if this has anything to do with this..but then on the other hand, the other "basis" transactions run just within half a second.

There are no swaps anywhere in the system in ST02.

We have tried implementing the latest support stacks on both the ABAP/JAVA stacks, but it looks like something else. The RAM is 12 GB's and 5 CPU machine...
